I personally believe within a pretty short time we'll see females will be relatively more succesful at poker than males.
Why ?? well, just because while being outnumbered by the males playing if we look at absolute numbers, the percentage of females taking a real serious approach, compared to all the percentage of males taking a serious approach will be much higher.
Besides from that, and don't come with nonsense like male are smarter, female bluff less, female can't be as agressive as male....that's all BS, women have one advantage compared to a lot of male players.....their decisions are way less influenced by a high testosteron level, which I'm pretty sure , loads of male players suffer from.
